Abstract

PURPOSE

To ascertain whether the refractive, visual, and intraocular optical quality outcomes
of a rotationally asymmetric multifocal intraocular lens (IOL) are enhanced by the
use of a capsular tension ring.

METHODS

Ninety consecutive eyes from 53 patients (age range: 36 to 82 years) were divided
into two groups: the no ring group comprised 43 eyes implanted with the multifocal
rotationally asymmetric Lentis Mplus LS-312 (Oculentis GmbH) without a capsular tension
ring; and the ring group comprised 47 eyes with the same IOL with a capsular tension
ring. Distance and near visual acuity and refractive outcomes were evaluated pre-
and postoperatively. Contrast sensitivity, intraocular aberrations, and defocus curve
were evaluated postoperatively.

RESULTS

Significant postoperative differences between groups were found in sphere, spherical
equivalent refraction, and near addition (P<.02). Regarding defocus curve, significantly
better visual acuity was present in eyes with the capsular tension ring for intermediate
vision conditions (P<.05). Intraocular aberrometry did not differ significantly between
groups (P<.09).

CONCLUSIONS

Refractive predictability and intermediate visual outcomes with the Lentis Mplus LS-312
IOL improved significantly when implanted in combination with a capsular tension ring.
